VIDEO QUALITY ENHANCEMENT AND/OR ARTIFACT REDUCTION USING CODING INFORMATION FROM A COMPRESSED BITSTREAM

摘要

A system and method of processing a digital video signal for display on a display device, includes decoding an encoded digital video signal to produce a decoded digital video signal having a video source format; extracting coding information from the encoded digital video signal; executing a video quality improvement algorithm on the decoded digital video signal having the video source format using the extracted coding information, to produce a processed decoded digital video signal having the video source format; and converting the processed decoded digital video signal from the video source format to a video display format suitable for display on the display device. The system and method enhance the quality and/or reduce video artifacts in a video signal after it is decoded and prior to display on a display device. ® KIPO & WIPO 2007
